Context Not Being Included: app-anouncement-xx-custom

And therein lies the problem:

[root@agents ~]# rasterisk -x 'dialplan show @app-announcement-16'
[ Context 'app-announcement-16' created by 'pbx_config' ]
  'fax' =>          1. Goto(${CUT(FAX_DEST,^,1)},${CUT(FAX_DEST,^,2)},${CUT(FAX_DEST,^,3)}) [pbx_config]

-= 2 extensions (7 priorities) in 1 context. =-

The custom file is included AFTER the announcement.

I re-wrote my application to put the whole [app-announcement-XX] in extensions_override_freepbx.conf and that finally made it work. It updates about 600 announcements to run an AGI BEFORE the announcement.
